Rent increase rules in England: a complete guide for tenants

If your rent is going up, the first thing to know is: there are rules. Your landlord cannot simply pick a number and demand more money. There is a legal process they have to follow — and if they get it wrong, the increase may not be valid.

This guide covers how rent increases work in England, what notice your landlord must give, how often they can raise your rent, and what's changing when the Renters' Rights Act 2025 comes into force on 1 May 2026.

Types of tenancy and how rent increases work

How your rent can be increased depends on the type of tenancy you have.

Periodic tenancy (rolling month-to-month or week-to-week) Most renters in England are on an assured shorthold tenancy (AST) that has rolled into a periodic tenancy after the initial fixed term ended. If that's you, your landlord must use a Section 13 notice — a prescribed government form — to propose an increase. A casual email, letter, or text message is not enough.

Fixed-term tenancy If you're still within a fixed term (for example, a 12-month contract), your landlord generally cannot increase the rent until the fixed term ends — unless the tenancy agreement contains a specific rent review clause. Even then, from 1 May 2026, those clauses will no longer be valid (more on that below).

The key point: for most private renters in England, Section 13 of the Housing Act 1988 is the main legal mechanism for rent increases. From May 2026, it becomes the only one.

How much notice must your landlord give?

Your landlord cannot spring a rent increase on you overnight. They must give you advance notice using the correct form, and the minimum notice period depends on when the notice is served.

Current rules (before 1 May 2026)

The notice period depends on how often you pay rent:

How you pay	Minimum notice
Weekly or fortnightly	1 month
Monthly	1 month
Yearly	6 months

The new rent can only take effect from the first day of a new tenancy period after the notice expires.

New rules (from 1 May 2026)

The Renters' Rights Act 2025 simplifies this: all tenancies require a minimum of 2 months' notice, regardless of how often you pay rent. This gives you more time to prepare, compare market rates, and decide whether to challenge.

If the notice period on your form is shorter than the legal minimum, the notice is not valid.

How often can your landlord increase rent?

Your landlord cannot keep raising the rent every few months. Under both current and upcoming rules:

• Rent can only be increased once every 52 weeks. The clock starts from the date the last increase took effect — not when it was proposed.
• No increase during the first year. From 1 May 2026, your landlord cannot serve a rent increase notice during the first 12 months of a tenancy.

So if your rent went up last July, the earliest the next increase can take effect is the following July. If a notice arrives sooner than that, it is not valid.

Does the increase have to be "fair"?

There is no official cap on how much a landlord can increase rent in England. The proposed amount should reflect the open market rate — what a similar property in the same area would rent for on the open market, in its current condition.

That said, "market rate" is not an exact science. Landlords sometimes propose amounts well above what comparable properties charge, whether intentionally or because they haven't checked.

Here is where your rights come in. If you believe the proposed rent is above market rate, you can:

1. Negotiate directly with your landlord — many prefer to agree a compromise rather than go through a formal process.
2. Apply to the First-tier Tribunal (Property Chamber) for an independent market rent determination. The tribunal is not a court — it is a specialist panel, and applying is free of charge.

The tribunal will look at comparable rents in the area, the condition of the property, and any relevant factors before deciding what a fair market rent should be.

What the Renters' Rights Act 2025 changes

The Renters' Rights Act 2025 comes into force on 1 May 2026 and introduces significant protections for tenants. Here is what changes for rent increases:

• Section 13 becomes the only method. Contractual rent review clauses in tenancy agreements are void. Landlords must use a Section 13 notice for every increase, no exceptions.
• New prescribed form (Form 4A). The current Form 4 is replaced. Any notice served on or after 1 May 2026 using the old form will be invalid.
• Minimum 2 months' notice for all tenancy types, regardless of payment frequency.
• No increase in the first 12 months of a tenancy.
• The tribunal can only keep rent the same or reduce it. Under current rules, the tribunal can set a rent higher than what your landlord proposed — a risk that deters many tenants from challenging. From May 2026, that risk is removed entirely.
• No backdating. Currently, a tribunal decision is backdated to the date in the notice. From May 2026, any new rent only applies from the date of the tribunal's decision.
• Hardship delay. The tribunal gains the power to delay the start of an increase by up to 2 months if paying the higher rent would cause you hardship.

These changes remove the biggest barriers to challenging — making it safer and more straightforward for tenants to exercise their rights.

What to do if you think your increase is wrong

If you have received a rent increase notice and something does not look right, here is a simple process to follow:

1. Check the notice is valid. Look at the form, the dates, the notice period, and whether 52 weeks have passed since the last increase. Even small errors — a wrong date, the old form, or a short notice period — can make the notice invalid.

2. Compare market rates. Search for similar properties in your area on Rightmove, Zoopla, or OpenRent. Are they asking the same rent, more, or less? This gives you a sense of whether the proposed increase reflects the market.

3. Talk to your landlord. If the increase seems high, a polite conversation or email can go a long way. Many landlords would rather negotiate than risk a tribunal referral. Put any agreement in writing.

4. Apply to the tribunal. If you cannot agree and the proposed rent is above market rate, you can apply to the First-tier Tribunal. It is free, you do not need a solicitor, and from May 2026 there is no risk of the rent being set higher than what was proposed.

The deadline matters: you must apply to the tribunal before the date the new rent is due to take effect. Miss it and the increase goes ahead automatically.

Key takeaways

• Your landlord must follow a legal process to increase your rent — a casual message or letter is not enough. Section 13 is the main mechanism, and from May 2026, the only one.
• The minimum notice period is currently 1 month for most tenancies, rising to 2 months for all tenancies from 1 May 2026.
• Rent can only go up once every 52 weeks, and from May 2026, not during the first year of a tenancy.
• There is no cap on the amount, but it must reflect the open market rate — and you have the right to challenge at the tribunal if it does not.
• From May 2026, challenging is risk-free: the tribunal can only keep rent the same or reduce it, never increase it.

Frequently asked questions

How often can my landlord increase my rent?

Your landlord can only increase your rent once every 52 weeks. The gap is measured from the date the last increase took effect. From 1 May 2026, they also cannot serve a notice during the first 12 months of a new tenancy.

Is there a limit on how much my landlord can increase rent?

There is no percentage cap or fixed limit. However, the proposed rent must reflect the open market rate for a similar property in the same area. If it is above market rate, you have the right to challenge it at the First-tier Tribunal.

What happens if my landlord does not use a Section 13 notice?

On a periodic tenancy, a rent increase is only valid if it follows the Section 13 process using the correct prescribed form. If your landlord sent the increase by email, letter, or any other method, it has no legal effect and you are not required to pay the higher amount.

Can I challenge a rent increase even if the notice is valid?

Yes. A valid notice means the paperwork is correct — it does not mean the proposed rent is reasonable. If you believe the amount is above the market rate for your area, you can apply to the First-tier Tribunal for an independent determination. From May 2026, the tribunal can only keep your rent the same or reduce it.

What is the Renters' Rights Act 2025?

The Renters' Rights Act 2025 is legislation that reforms the private rented sector in England. Key changes for rent increases — coming into force on 1 May 2026 — include making Section 13 the only method, requiring 2 months' minimum notice, and preventing the tribunal from setting rent higher than what the landlord proposed.

Do I need a solicitor to challenge a rent increase?

No. The tribunal process is designed to be accessible without legal representation. Applying is free of charge, and many tenants handle the process themselves. Tools like RentSOS can help you check your notice and understand your grounds before you decide.
